Deck Wetness and Extreme Motions Experiments: An Investigation into Establishing Reliable Statistics for Rare Events

Abstract

Experiments to establish reliable statistics for rare events such as deck wetness have been carried out at Haslar. A model of the S-175 container ship was tested at one speed in irregular head waves (one wave spectrum, different time histories). The results suggest that a minimum total run length of 200 model lengths is required before a reasonably reliable estimate of the deck wetness frequency can be obtained. Three hundred would represent good practice. Keywords: Ship models; Ship hull forms; ITTC wave spectrum; Water waves; Container ships; Slamming; Ship bow motion; Ship decks. Great Britain.
